Hello folks, ok, the color boards are available! First off, I'd like to give a big thanks to Bill at Pangolin for his contribution in making this happen. I wanted to come up with a hybrid version of the simple Sallen Key circuit he has on his website, jazzed up with some other features and I really appreciate his input and guidance in making this a well rounded circuit. It still blows me away at how much time he dedicates to us hobbiest. Thanks Bill!
I'd also like to thank Buffo for spending a weekend with me installing one of these color boards in his projector, plus the time he's spending on writing the tutorial on how to tune them!
So there you have it, the boards are available. I ask that you read through Buffo's mini-review of the board http://www.photonlexicon.com/forums/...63&postcount=1.
Basically, the board has a differential to single ended input stage. You can feed it either a differential or single ended signal and the output stays the same. There are two diodes in the circuit which keep the output within -.3 to +5.1V. The total current draw on the test board I have here is around 50mA per supply side. The board can be run from you scanner amp power supply IF the output doesn't exceed 25VDC per side (ie. +25VDC to -25VDC). It would seem that most scanner supplies are +24VDC to -24VDC, check before you connect!
Regarding availability, I have limited stock built and tested at this point, if you place your order and I'm sold out, there could be a delay. I'll email you when your order is received to let you know, or feel free to send me a PM to check the status of stock.
Due to the difficulties in tuning this board, I'm offering a 15 day money back guarantee. See the website for details.

For a quick idea of what it does (this is also posted on my website) Here's a before and after pic of a test pattern.
